Abstract: A method and apparatus may include aligning a reference image and an input image through ROI-based image alignment; detecting an ROI associated with an incompletely aligned region in the aligned image; and blending the aligned reference image and input image by using a plurality of weights which are attenuated according to a spatial distance from a boundary of the detected ROI. In addition, the method and apparatus may include aligning a reference image and an input image through image alignment based on an nth region of interest (ROI) which is detected at a previous stage; detecting another ROI associated with an incompletely aligned region in the aligned image; and blending the aligned image in the other ROI and an (n+1)th blended image, which is input from a next stage, in a region outside the other ROI, and outputting the last blended image to the previous stage.

Abstract: Disclosed herein are an X-ray imaging apparatus and an X-ray image generating method in which constituent materials of a target object are separated and mapped to different colors in order to provide one image which has improved distinction between tissues. The X-ray imaging apparatus includes an X-ray generator which generates X-rays and irradiates the X-rays toward a target object, an X-ray detector which acquires X-ray data which corresponds to a plurality of energy bands by detecting X-rays which have passed through the target object, and a controller which acquires a plurality of material images in which a plurality of materials constituting the target object are respectively displayed and brightness information from the X-ray data, generates one image by mapping different color channels to the plurality of material images and combining the plurality material images into a single image, and applying the brightness information to the generated image.
